ATTORNEY Patented July 22, 1930 JAMES L. RICE, or Los ANGELES, CALIFORNIA REAR-VISION MIRROR applicati@ mea December 1s, 1927. seran No. 239,673.

This invention vrelates to automobile accessories and particularly to rear vision mirrors.

The principalobject of my invention is to 5 provide as a single unit a Wind shield wing having a rear vision mirror formed thereon or directly attached thereto. This device would have, therefore, particular value for use on open cars in which such Wings are counted as almost a necessity and in which the back curtain-windows are sometimes so small that it is hard to locate an interior rear vision mirror so as to be effective.

A further object is to arrange the mirror so that proper reflection therefrom will not be impaired when the angle of setting of thc wings is altered and no corresponding adj ustment of the mirror is necessary with any such adjustment of the wing.

A further object of the invention is to produce a simple and inexpensive device and vet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure ad relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

' ln the drawings similar characters of reference indicate corresponding parts in the several views: A

Fig. 1 is a perspective outline of a motor vehicle showing my combined wing and mirror attachment.

Fig..2 is an enlarged fragmentary section of a wing taken through the mirror.

Fig. 3 is a similar view showing a modied method of forming the mirror` Referring now more particularly to the numerals of reference on the drawings, and particularly at present to Figs. 1 to 3, 1 denotes the wind shield Wings which as usual are flat plate glass panels of suitable size having brackets 2 for attachment to the frame 3 of the wind shield of the car.

Disposed in eachvwing adjacent its lower and outer edge is the mirror 4. This mirror is of circular form and is convex relative to the rear face of the wing. It may be made as an element separate from and cemented onto the o Wing as shown in Fig. 2, or made integral therewith. This is done by forming the wing during its manufacture with a depression on oneside to give a bulge of the desired size on the other side as shown at 4" in Fig. 3.

The mirror ell'ect from the convex portion 55 is of course obtained by placing a layer of reflecting metal 5 as usual on the concave front face of the mirror area as shown.

By reason of this construction it will be seen that ih either case the convex or outer 3,0 surface of the mirror has a reflecting area concentric with and practically equal to the area. of said convex surface. The reflection therefore from any point of themirrored surface will be equal throughout and will not be distorted in any way.

The mirror is preferably mounted in both wings and by reason of the particular shape employed it will be evident that adequate and enlarged reflection from the rear will be obtained by the driver of the car regardless of any adjustment or setting of the wings. j

From the foregoing-description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention, as set forth herein.

While this speilication sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail maybe resorted to as do not form 30 a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure -by Lettersi Patent v 85 1. A windshield wing comprising a transparent and mainlyI flat-surfaced body, said body being formed with a spherically curved portion projecting convexedly from its rear surface, the front faceof the body being concavely curved concentric with said convexly curved portion and the thickness of the bdyr between said curved portions being such that the area of the concave surface is substantially the same as thatpf the convex portion, and a metallic reflecting coating over said concave surface. v f.

2. A windshield wing comprising a transarent and mainly flat surfaced body, said ody having a sphercally curved element 10 projecting convexedly from its rear surface, the front face of said element being concarvely curved concentric with the convexly curved surface and of substantially the same area,

5 and a metallic reflecting coating over said concave surface.

In testimony whereof I ax my signature.

JAMES L. RICE.
